Add ability to specify multiple input files to the selabel_open.
The file_contexts labeling backend, specified in label_file.c, currently assumes
that only one path will be specified as an option to selabel_open(). The split
of platform and non-platform policy on device, however, will necessitate the
loading of two disparate policy files. Rather than combining the files and then
calling the existing API on a newly-formed file, just add the ability to specify
multiple files to use. Order of opt specification to selabel_open matters.
Bug: 31363362
Test: Device builds and boots w/no additional denials with split context files.
